Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 197 words
A color photographic material having a silver halide emulsion layer coated on a support in which the silver halide emulsion layer contains an acylacetanilide yellow coupler having at the acyl or anilide portion thereof a moiety represented by the following formula I: --X--Y--Z I wherein X--Y in the formula I is selected from a group consisting of ##STR15## wherein X is --NHCO-- or --CONH--, wherein Z is ##STR16## wherein R 1 is an alkyl or aryl radical, and R 2 is a hydrogen atom or an alkyl or aryl radical, and wherein a residue of the yellow coupler to which the moiety represented by formula I is attached is represented by the following formula II: ##STR17## wherein the moiety represented by the formula I is attached to R 3 or the benzene ring, R 3 represents an alkyl or aryl radical; A represents a halogen atom, an alkyl radical, an alkoxy radical, or an aryloxy radical; B is a halogen atom, an alkyl radical, an alkoxy radical, or an aryloxy radical; n is 0 or 1; R 4 is a radical separable at the time of the coupling of the oxidized product of developing agents with couplers.
